David vs. Goliath: Upsets of the Week

by Candidate Master Peter Zhdanov

In this special weekly column we will be looking at the most unexpected upsets that happened last week. Players usually face opponents of a comparable level. Considerably less frequent are situations when a significantly lower-rated player succeeds in beating a much stronger adversary.

This week's post includes many games from junior chess championships where many underrated players are participating. Hence, it is not surprising that our hit list looks rather impressive:

Top-10 upsets:

Mikes (2102) - Deary (1602), 0-1, 500 points (new record!)
Mamyrbay (1590) - Abbas (2016), 1-0, 426 points
Stark (1983) - Pereira (1571), 0-1, 412 points
Oltian (1799) - Sofranov (2191), 1-0, 392 points
Mamyrbay (1590) - Rohrer (1976), 1-0, 386 points
Jarc (1698) - Badalyan (2081), 1-0, 383 points
Deary (1602) - Gonzalez Olivieri (1985), 1-0, 383 points
Ahmed (1935) - Gjika (1563), 0-1, 372 points
Liu (1909) - Beukema (2274), 1-0, 365 points
Pricopie (1630) - Kjoita (1992), 1-0, 362 points

Average gap: 398 points (new record!); White won 7 games, Black won 3 games

Sunday Puzzle-27

The Hardest Ever Logic Puzzle

Although the following is a new puzzle, its method of solution can be derived from a similar puzzle credited to George Boolos and often referred to as ―The Hardest Logic Puzzle Ever. 

A prisoner in solitary confinement, who has no idea what day of the week it is, has been told that on each day for three consecutive days he can ask the guard on duty a question to which he will receive a 'yes' or 'no' answer. From the responses, he must announce on the third day what day of the week it is. If he is correct he will be set free, if not he will be executed.

The prisoner is faced with several difficulties. A guard will either consistently tell the truth or consistently lie and on no two days of a week will the guard be the same man. Furthermore, although the guards understand English, they have been instructed to give a 'ho' or a 'mo' answer, one of them meaning 'yes' and the other meaning 'no'. The prisoner has no idea which is which. 

What line of questioning is sure to win the prisoner his freedom?

Anna Ushenina is the New Women's World Chess Champion

User Rating: / 11

http://www.pogonina.com/images//usheninawwcc.jpg

Anna Ushenina (born August 30, 1985) from Ukraine became the XVth Women's World Chess Champion after beating ex-Women's World Chess Champion and the reigning Women's Rapid Chess Champion Antoaneta Stefanova in the final match on tie-breaks in rapid chess. Additionally, Anna has earned the GM title, a $60,000 paycheck and the right to face Hou Yifan in a World Championship match next year.

Ushenina was rated #38 among women in the world before the championship, and very few people were expecting her to succeed. However, by taking a look at her recent results once can notice a dramatic improvement in her performances: she was undefeated in the Chess Olympiad and Ukrainian Women's Championship, as well as in all the games until the final classical one vs. Stefanova (which she lost rather poorly and awkwardly). Here is a reminder of what her tournament run looked like:

1/32-final: Ushenina (2452) - Cori Deysi (2429): 1.5-0.5
1/16-final: Ushenina (2452) - Muzychuk A (2586): 3-1
1/8-final: Ushenina (2452) - Pogonina (2478): 1.5-0.5
1/4-final: Ushenina (2452) - Kosintseva N (2539): 1.5-0.5
1/2-final: Ushenina - Ju Wenjun (2501): 2.5-1.5
Final: Ushenina (2452) - Stefanova (2491): 3.5-2.5

The winning line is easy to find, but still very elegant.
